It would be E) imo

Stmt I

k=8 no
k=16 yes

insuff

Stmt II

Let k = 2*3*5*7 NO
K=2^2*3^2*5^2*7^2 YES

insuff

Stmt I and II

k = 2^2*3^2*5^2*7^2 satisfies both conditions and is square of an integer

k= 2^3*3^2*5^2*7^2 satisfies both conditions and is not a square of an integer

INSUFF


Choose E)
